Cover attachment

Abstract

An airbag assembly includes a module with a base plate, an airbag, and a housing for the airbag; and a cover removably attached to the module. The cover can be attached to the housing or base plate without fasteners. An outward extending locking piece is configured to attach to an opening to lock the cover, housing and base plate together. The base plate can also include locking tabs configured to fit in corresponding notches in the cover.

1. An airbag module, comprising:
 a base plate; 
 an airbag; 
 a housing for the airbag; and 
 a cover removably attached to the module, 
 wherein the base plate includes a locking tab extending from a circumferential edge of the base plate and configured to fit into a corresponding notch in the cover, 
 wherein the base plate includes an outward extending locking piece configured to attach to the cover, and 
 wherein the cover includes an opening to receive the locking piece, and the opening includes a guide lock to prevent the locking piece from sliding out of the opening. 
 
   
   
     2. The airbag module of  claim 1 , wherein the notch is positioned in a top edge of the cover. 
   
   
     3. The airbag module of  claim 1 , wherein the locking piece extends from an end wall of the base plate. 
   
   
     4. The airbag module of  claim 1 , wherein the locking piece comprises a base and a top portion, the top portion includes a flange that overhangs a portion of the base. 
   
   
     5. The airbag module of  claim 1 , wherein the locking piece comprises an extending section approximately perpendicular to a wall of the housing, and a hook section at a distal end of the extending section. 
   
   
     6. An airbag module, comprising:
 a base plate; 
 an airbag; 
 a housing for the airbag; and 
 a cover removably attached to the module, the cover including a top wall and a side wall, 
 wherein the cover includes a locking piece extending from inner surface of a side wall of the cover, and the locking piece being configured to attach to the housing, and 
 wherein the housing includes an opening for receiving the locking piece, the opening including a guide lock to prevent the locking piece from sliding out of the opening. 
 
   
   
     7. The airbag module of  claim 6 , wherein the opening comprises an entrance opening portion and a locking portion,
 wherein the locking portion is narrower than the opening portion. 
 
   
   
     8. The airbag module of  claim 6 , wherein the base plate includes an opening for receiving the locking piece. 
   
   
     9. The airbag module of  claim 8 , wherein the base plate opening comprises an entrance opening portion and a locking portion,
 wherein the locking portion is narrower than the opening portion. 
 
   
   
     10. The airbag module of  claim 6 , wherein the locking piece comprises a base and a top portion, the top portion includes a flange that overhangs a portion of the base. 
   
   
     11. The airbag module of  claim 6 , wherein the locking piece comprises an extending section approximately perpendicular to an interior wall of the cover, and a hook section at a distal end of the extending section. 
   
   
     12. An airbag module, comprising:
 a base plate; 
 an airbag; 
 a housing for the airbag; and 
 a cover removably attached to the module, the cover including a top wall and a side wall, 
 wherein the base plate includes an outward extending locking piece configured to attach to an opening in the side wall of the cover, and 
 wherein the opening includes a guide lock to prevent the locking piece from sliding out of the opening. 
 
   
   
     13. The airbag module of  claim 12 , wherein the opening comprises an entrance opening portion and a locking portion,
 wherein the locking portion is narrower than the opening portion. 
 
   
   
     14. The airbag module of  claim 12 , wherein the locking piece comprises a base and a top portion, the top portion includes a flange that overhangs a portion of the base. 
   
   
     15. The airbag module of  claim 12 , wherein the locking piece comprises an extending section approximately perpendicular to a wall of the base plate, and a hook section at a distal end of the extending section. 
   
   
     16. The airbag module of  claim 12 , wherein the base plate includes a locking tab extending from a circumferential edge of the base plate and configured to fit into a corresponding notch in the cover.
